On a cold day, the temperature in a certain city changed −23.8°F over 6.8 hours. What was the average change in temperature per hour? Enter your answer as a decimal in the box.

Answer:

-9+30x

Step-by-step explanation:

-3 x 3 is -9

-3 x -10x is 30x

Answer:

-9 + 30x

Step-by-step explanation:

Like you mentioned, to solve this expression we need to use the distributive property...

We have to distribute -3 to 3 and -10x.

When multiplying negative and positive numbers it is important to know that...

-negative times negative equal positive

-negative times positive equal negative

-3 · 3 = -9

-3 · -10x = 30x

Therefore the answer is -9 + 30x

Step-by-step explanation:

♤ 3(b-5) = 27

=> 3b - 15 = 27

=> 3b = 27 + 15 = 42

=> b = 42/3

=> b = 14 (Ans)

♤ 2x/3 = 6

=> 2x = 6 × 3 = 18

=> x = 18/2

=> x = 9 (Ans)

♤ 2(n + 5) = 15

=> 2n + 10 = 15

=> 2n = 15 - 10 = 5

=> n = 5/2

=> n = 2.5 (Ans)

♤ a + a + a + a = 24

=> 4a = 24

=> a = 24/4

=> a = 6 (Ans)

♤ 4c + 6 = 18

=> 4c = 18 - 6 = 12

=> c = 12/4

=> c = 3 (Ans)

Answer:

y = 3/4x + 27/2

Step-by-step explanation:

y2 - y1 / x2 - x1

7 - 1 / 6 - (-2)

6 / 8

= 3/4

y = 3/4x + b

9 = 3/4(-6) + b

9 = -9/2 + b

27/2 = b

Answer:

1.7

Step-by-step explanation:

in one hour, the first pump can fill the tank 1/4 of the way

in one hour, the other can fill it 1/3 of the way.

get them to the same denominator.

3/12+4/12=7/12 of the tank in one hour

1÷7/12=12/7=1 5/7=1.7

The amount of commission expense that will appear on the flexible budget if 2900 units were sold is; $11600

The activity variance is favourable.

According to the question;

To solve this;

We must be aware that the commission expense is directly proportional to the number of units sold.

In essence;

By cross product;

Ultimately, the activity variance is favourable bas less commission expense is recorded for less sale.

Answer:

Length=4 cm

Step-by-step explanation:

Solve for L

L*W=A

16 cm^2=L*W

Since this a square. W will equal L.

So [tex]\sqrt{16} =4[/tex]

Meaning that the length is 4    

The area of a square is given by:

Area = Side²

If the area of a square is 16 square centimeters, the side length of the window is 4 cm.

A square is a four-sided polygon, whose all sides are equal in length and whose opposite sides are parallel to each other.

We have,

Area of the square = 16 square centimeters

The area of a square is given as:

Area = side²

Area = 16 cm²

16 cm² = side²

Square root on both sides
[ 4² = 16 ]

√16 cm² = √side²

Side = 4 cm

Thus if the area of the square is 16 square centimeters, the side length of the window is 4 cm.

Answer:

Step-by-step explanation:

7(0)+y=10

y=10

Answer: (0, 10)

Step-by-step explanation:

The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.

The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.

To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.

[tex]7x+y=10\\[/tex]

[tex]7(0)+y=10[/tex]

[tex]0+y=10[/tex]

[tex]y=10[/tex]

As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].
